The aim of this study was to investigate the relationships between eye discomfort symptoms and work with visual display terminals among routine office workers.
Three hundred and twenty-seven office workers and their work stations were investigated by means of questionnaires and worksite investigations. The data were subjected to multivariate logistic regression analyses.
The occurrence of eye discomfort increased as the extent of VDT work increased, as did the specific symptoms of sensitivity to light and smarting, gritting feeling, or redness. The use of spectacles during visual display terminal work, age, stomach stress reaction, distances between the eye and different visual task objects, as well as the vertical position of the terminal also influenced certain symptoms. Having (i) the terminal at about eye level during prolonged terminal work, (ii) using monofocal glasses during terminal work in situations with large distance variations to visual task objects, or (iii) being elderly with prolonged terminal work and reporting stomach stress all led to increased odds ratios for certain eye discomfort symptoms.
The use of a visual display terminal in routine office work is associated with an increased occurrence of certain eye discomfort symptoms. This association is affected also by the presence of certain other individual and ergonomic factors.
本研究旨在调查日常办公人员的眼部不适症状与视觉显示终端工作之间的关系。
通过问卷调查和工作场所调查对327名办公人员及其工作场所进行了研究。对数据进行多因素逻辑回归分析。
随着VDT工作时长增加，眼部不适的发生率上升，对光敏感、刺痛、有磨砂感或眼睛发红等特定症状的发生率也上升。在视觉显示终端工作时佩戴眼镜、年龄、胃部应激反应、眼睛与不同视觉任务对象之间的距离以及终端的垂直位置也会影响某些症状。在长时间终端工作期间将终端置于大约眼睛水平高度、在与视觉任务对象距离变化较大的情况下于终端工作时佩戴单焦点眼镜、或者是长时间从事终端工作且报告有胃部应激反应的老年人，均会导致某些眼部不适症状的比值比增加。
日常办公工作中使用视觉显示终端与某些眼部不适症状的发生率增加有关。这种关联还受到某些其他个人因素和人体工程学因素的影响。
